### SPV Workshop

This is a brief exercise on validating SPV Proofs using `bitcoin-spv`. It

includes one contract (`SPVLogger.sol`) that verifies payments made to James.

Your goal is to implement a Bitcoin SPV system. We've provided tests that

include a valid proof, and built all the libraries you'll need to evaluate it.

### Warning

THIS IS NOT INTENDED FOR PRODUCTION AND THE CODE DOES NOT ACCOMPLISH SECURE SPV

COMMUNICATION. IT IS FOR EDUCATIONAL PURPOSES ONLY

### How to play :)

Clone this repo and run:

```bash

$ npm i -g truffle

$ npm i

$ truffle test

```

You'll see that the tests do not pass. The `SPVLogger` contract is not fully

implemented! You'll need to go through the file and fill lines around each

comment starting with `// Goal`. They'll have instructions, and always use one

or more of [BytesLib](https://github.com/summa-tx/bitcoin-spv/blob/master/solidity/contracts/BytesLib.sol),

[BTCUtils](https://github.com/summa-tx/bitcoin-spv/blob/master/solidity/contracts/BTCUtils.sol),

or [ValidateSPV](https://github.com/summa-tx/bitcoin-spv/blob/master/solidity/contracts/ValidateSPV.sol).

The answers can be found by switching to the `working` branch.

But that's cheating :)
